key mixing strategy and uses a simpler (faster) bit distribution function.
Note: read about important differences between hash and scatter sets.

ByteShortHashMap
The default implementation mixes the hash of the key with ByteShortHashMap.keyMixer
to differentiate hash order of keys between hash containers. Helps
alleviate problems resulting from linear conflict resolution in open
addressing.
The output from this function should evenly distribute keys across the entire integer range.
